Lessons in this topic
- BTP Application Logging Part 1: Why Logs Matter on BTPLearn how BTP applications produce and store logs: log levels, structured JSON logs, the application logging/observability services for Cloud Foundry, dashboards for search, and the difference between application logs and Integration Suite message processing logs.
- BTP Application Logging Part 2: Configuring and Consuming Logging on Cloud FoundrySet up logging for Cloud Foundry apps: create and bind the logging service instance (via MTA), use SAP logging libraries for Java and Node.js to produce structured logs, set log levels dynamically, mask sensitive data, and manage retention and cost.
- BTP Application Logging Part 3: Log Correlation and Troubleshooting Across ServicesTrace one business request across app router, CAP services, external APIs and integration flows using correlation IDs; combine application logs with Integration Suite message processing logs; and run a structured troubleshooting approach for distributed BTP solutions.
Interview questions covered
- What are the core concepts of Application Logging, and how would you explain them clearly in an SAP interview?
- How would you apply Application Logging in a real SAP project? Walk through the design or implementation approach.
- A production issue is reported in Application Logging. What would you check first, and how would you troubleshoot it systematically?
- What are the most important design decisions, trade-offs, and best practices in Application Logging?
- Suppose you inherit an existing Application Logging solution. How would you review it before making a change?
- An order confirmation fails sometimes across app router, CAP and an iFlow. How do you trace and fix it?
- Configure logging for a CAP application on Cloud Foundry.
- Support can't diagnose intermittent failures in a BTP app because logs are unstructured and short-lived. What do you set up?
